Strength and Creep-Fatigue Analysis of a Molten-Salt Storage Tank

Compared with photovoltaic power generation, a solar thermal power station needs a large energy storage system to achieve stable output of power. Molten-salt storage tank is the key equipment of a solar thermal power station so that the research on molten-salt storage tank is of great significance to the efficient and safe use of solar energy. In this paper, strength and creep-fatigue analysis was carried out on the tank by using finite element method. Based on related codes, strength and creep-fatigue assessment of the tank was completed. This work provided a valuable reference in the aspect of design and safety evaluation of large storage tank with high temperature.
